Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010 Configuration Manual page 105

To specify a nondefault time interval in the range 5–30 seconds (for ATM VCs)
or 5–300 seconds (for ATM VPs) at which the router calculates bit rate and packet
rate statistics, use the optional load-interval keyword. The default time interval
for either command is 5 seconds.
To display the time at which the router calculates bit rate and packet rate statistics
for the current interval, use the optional display-time-of-day keyword.
To stop either command, press Ctrl+c.
Field descriptions
Interface Interface identifier for the ATM interface on which the VC or VP
resides
VCD Virtual circuit descriptor that identifies the VC (monitor atm vc
command only)
VPI Virtual path identifier of the PVC (monitor atm vp command only)
Seconds between polls Number of seconds at which the router calculates
bit rate and packet rate statistics
Input bps/pps Number of bits per second (bps) and packets per second
(pps) received on this interface during the specified load interval
Output bps/pps Number of bits per second (bps) and packets per second
(pps) transmitted on this interface during the specified load interval
Time Time of day, in hh:mm:ss format, at which the router calculates the
bit rate and packet rate statistics for the current interval
Example 1 Displays bit rate and packet rate statistics over the default (5-second)
load interval for a single ATM VC
